Hysteresis data points have elsewhere appeared as "Magnetic hysteresis loop of Gd-SPIONs and AuNFs@MPS"
"Figure 2. FE-SEM image of (A) GO, (B) GO/silane@MNPs; (C) FE-SEM, (D) TEM, and (E) HR-TEM images of dendritic monomer; (F) FT-IR spectra of (a) Eu (III)-imprinted polymer, (b) after rebinding, and (c) extraction."
The three spectra in 2F are indistinguishable from three copies of the same line, with vertical offsets and a horizontal offset for spectrum (b).
